CASH AND PARCEL CARRIER.

SPECIFICATION forming part of Letters Patent No. 405,332, dated June 18, 1889.

' Application filed February 28, 1889. Y Serial No. 301,528. (No model.)

To all whom it may concern:

Be it known that I, EDGAR B. SrooKINe, a citizen of the United States, residing at IVashington, in the District-of Columbia, have invented certain new and useful Improvements in Cash and Parcel Carriers, of which the following is a specification, reference being had therein to theaccompanying drawings.

This invention has relation to certain improvements in cash and parcel carriers,which improvements are, while capable of use in4 connection with various styles of store-service apparatus, more particularly intended to be applied or added to an apparatus involving a frictional propelling` device constructed and arranged as disclosed in a patent granted me January 29, 1889, and numbered 396,7 7 8.

One object of the invention is the construction of a station-bracket in such a form as to operatively support the propelling device in such a manner or position with relation to the hanger or post as to bring the strain of the pulling-cord in a line with said post, and thus obviate any depression, springing, or vibration of the parts at the station.

Another object of the invention is to simplify and reduce the number of parts comprised in the apparatus.

Other obj ects and Aadvantages of the invention will appear in the following description, and the novel features thereof will be particulaly pointed out in the claims.

Referring to the drawings, Figure I is a side elevation of an apparatus embodying my invention. Fig. 2 is an end elevation. Fig. 3 is a plan of the car. Figs. 4 and 5 are plans of the resistance device set for propeiling the car a long and a short distance, respectively. Fig. 6 is a vertical section on the line X X of Fig. I, and Fig. 7 a detail in side elevation and on an enlarged scale of a preliminary and partial propelling-device setting-spring.

Like letters refer to like parts in all the iigures of the drawings.

A represents the track, and B the station hanger or post, both of which are of any usual construction.

Crepresents the station arm or bracket, by either of which terms I mean any structure capable of operatively supporting a caf-prou pelling device. The bracket C comprises in its make-up a head or sleeve C', which is adapted to receive or to be secured to the post B. In this instance the sleeve is interiorly screw-threaded to 'lit the post B, which is also threaded to permit of a vertical adjustment of the bracket, and to firmly secure the same after adjustment a jam-nut B is provided.

The sleeve C is provided with a pair of depending legsV C2, having elongated bearings C3 for the axle EX of the propelling device. The legs may or may not be, as desired, extended in the form of car-guides C4. On the innerside and near the lower end of each leg C2 is mounted in bearings D a bearing- Wheel D, the function of which is to prevent the pressure of the propelling device against the car from deflecting the track A.

IVithoutincluding the car-guides, the above are the only essential characteristics of the bracket C; but to insure tlre parallelism of the propelling device with the track a brace C5 may be secured to or formed as a part of the bracket and extended to any desired fixed object. By connecting the brace with the track additional advantages are secured. In this instance the brace is slitted, as at C6, Fig. G, and provided with a clamp-screw C7, so that a firm connection of the brace to the track is secured, also one giving a long bearing-surface, so that any weakening of the track, as with ordinary set-screws, is obviated. The brace also serves as a support for a bumper CS, which may be seated in a recess C", (see dotted lines, Fig. 1,) formed in the brace, or may be in the form of a ring C10, mounted on and encircling the brace. (See dotted lines, Fig. G.)

E is the propelling device, and in this invention it is in the form of a wheel, the shaft or axle E of which passes through the bearings Cf, and is provided at each end with a pulley E for the pulling-cords E2, which are connected with a spreader E3 and merged in a handle E".

C1l are ordinary guide-eyes formed on the legs C2 for the cords E2.

Before or after passing the cords E2 through holes E3X in the spreaderhalf-hitches or loops E2X are formed, so that when from usage the cords break at the pulleys E the spreader may be lowered toprovide additional cord IOO for a new connection thereof with the pulleys. The spreader also aids in distributing the strain on the pulleys equally when force is applied to propel a car. It desired, the handle El may be on or a part of the spreader, as indicated by dotted lines ELX.

F represents the top of the car, which is in this instance the driving-surface on which the propelling device E operates.

F is the frame of the car, and it is U- shaped, and has mounted-therein the wheels F2, which run on the track A, which passes longitudinally through the frame. Lugs, screws, or rivets F3 serve to connect the top and frame.

F3X are openings or recesses formed in the top F to receive the upper portions of the wheels, thus contributing to compaetness. At the bottom of the frame is cast a heavy hollow case, collar, or ring F4, the thickness or depth of which is comparatively far beyond itsv requirements as to strength, this being for the purpose of giving such weight to the .caras will enable it to partake more effectively the force given by the propelling` device. To overcome as far as possible the rcsistance of the air when the car is moving, the extra thickness is disposed toward the ends of the car to produce an oval outline, with the longer axis disposed lengthwise of the car.

F5 is the cash or parcel receptacle or box, which is retained in the case F4 by a bayonetjoint or any other suitable connecting device. It is apparent that by increasing the diameter of the wheel with or without arranging the pulling-cord and longitudinal bearings parallel with each other a greater leverage can be secured, so that for longer tracks greater impetus can be imparted than for shorter tracks, and this without increasing at the same time the diameter of the pulleys E', so that a shorter length of cord would be paid off, and consequently the distance through which the hand of the operator travels would be the same, although the power required would be greater in accordance with the increase of the diameter of the wheel. In any case, however, as stated in my above-mentioned patent, the driving-wheel-the propelling device-may be larger or smaller, and the length of the driving-surface F may be -increased or diminished, so that the leverage may be as desired. In the propelling device therein and herein shown (which may or may not be adhered to as to size) less than the whole of the periphery thereof is actually employed in'propelling a car; but as a wheel is cheaper to manufacture than a sector and does not require particular disposition on the axle, as would a sector, a wheel is preferable. f Instead of changing the diameter or size of the propelling device in accordance with the distance the car is required to travel, I have shown one means directly and detachably connected with the car and notV connected with or operated by the pulling-cord; but any other form ol resistance device may be substituted.

The resistance device consists of one or a pair of spring-jaws G, mounted on the bracket at any suitable point-for example, on the brace (E5-and extended to receive the carbody F between them and to pass over projections F, formed at each end on the opposite sides of the car. The holding-faces of the jaws are preferably slightly inclined. Now by means of an adjusting-screw G the jaws are caused to more or less snugly embrace the body, sol that greater or less power must be exerted on the pulling-cords in order to free the car from the jaws, and therefore the car will be propelled a proportionately greater or less distance. The screw G2 serves to bind the j aws' upon the brace. If desired,

the spring-jaws may be mounted on the legs of the bracket back oi the guide-eyes C and project toward the brace, as indicated by dotted lines Y.

The operation of the invention will be apparent from the above description; but I will giveacondensed statement of the same. Taking the parts shown in the position in Fig. l, a downward pull on the handle draws thc wheel E against the driving-surface F, with a tendency to rotate the wheel outwardly at the point of contact. This rotation is prevented by the resistance devicethe jaws G. The projecting edges of the top of the car are brought upon the bearing-wheels D, thus preventing any sagging of the track. At the instant that the power applied tov the wheel overcomes the grip of the jaws (predetermined by adjustment) the car shoots out of the station along the track to its destination, where it is received by similar jaws similarly adj usted and by a similar propelling device, which the incoming car puts into position for its return. Thebracket is formed of a single casting and the car is of two castings, which reduces the number of parts and the cost of manufacture. The location of the post, propelling device, the socket, and pulling-cord secures a straight line of force and resistance, so that bending or vibrations of the post and bracket are obviated. If desired, the

propelling device and driving-surface maybe duplicated, as disclosed in my above-inentioned patent.

II, Figs. l and 7, represents a spring secured to the bracket and rprojecting into the path of a pin II on the cord-,pulley E. The object and purpose of this spring are to partially wind the pulling-cords on theirpulleys, whereby a limited portion of the driving-surface oi the propelling device beyond that which would be brought into position for use by an incoming car is utilized. In other words, a car when it enters a station causes the propelling device to rotate or partially rotate on its axis and winds up the pullingcords in accordance with said rotation of the propellin g device. I iind it advantageous to IOC) IIO

obviate any lost motion occasioned by a sudden contact of the car with the propeller or otherwise, and to provide for setting for use a longer distance of contact-surface of the propeller. This provision is made by the spring H.

Referring to Fig. 7, the full lines represent the parts at the instant a carF has been propelled from the station, and the dotted lines represent the position the parts assume by the action of the spring Il. As the car leaves the station, the cords E2 are taut and extend from the guide-eyes C11 on a line toward the center of the pulley, and the pin H is pressing the spring out of its natural position, thereby putting it under tension. As the operator releases the handle E4, the spring moves to its natural position, (indicated by dotted lines,) bearing against pin H', and causing the pulley E and propelling device E to partially rotate and Wind up a slight portion of the cords. An incoming car iinds a portion of the cords Wound and a portion of the contact-surface of the propelling device preliminarily set. It then Winds up additional cord and sets for use additional contactfsurface of the propeller, the extent of each being in accordance with the length of driving-surface of the said car which comes into contact with the propeller during an entrance of the car into the station. This is, as shown, less than the length of the car.

In my above-mentioned patent similar devices similarly arranged are provided to insure the rewinding of the cords-in that case the purpose being to obviate the necessity of rewinding the same by the incoming car, so that the present purpose is not only different, but the arrangement is diiferent inthat the spring is adjusted for partially Winding the cords and moving the propeller in position to operate after the portion Wound by contact with the car has been utilized in propelling the car. If a spring has a tension sufficient to insure Wholly the rewinding of the cord, it would act to prevent a satisfactory entrance of the car into the station unless means Were provided to prevent contact of an incoming car With the propeller; but in the present adj ustment of the tension of the spring it simply preliminarily Winds a slight portion of the cord, leaving the balance to be done by the entering car. I have found that this not only overcomes any accidental slipping of the parts one upon the other, but neutralizcs or obviates the effect of any lost motion otherwisc produced.
